camera applications</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>In your applications, you can embed other applications that provide services,
such as image capture and voice recording. For example, a multimedia messaging
service (MMS) editor could embed the camera application to capture images
and insert them in multimedia messages.</p>
<p>Use the New File Service Client API to create a service client.</p>
<note><p>The binary compatibility of the API plug-ins is not guaranteed either
between platform versions or within a platform version. Test your application
on each device model that the application can be installed on to ensure the
best possible user experience. To prevent application installation on other
than tested devices, define the product IDs (also called manufacturer IDs)
in the <xref href="GUID-7F1B2577-2FEF-45F9-B32F-745DFE0F0D95.dita">package file</xref>.
For more information, see <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/ToolsAndUtilities94/Installing-ref/PKG_format/PKG_dependency.html" format="application/java-archive">Hardware/UI platform dependency</xref>.</p></note>
